| Summary | 0031595: Strange behaviour on TListView onChange event | ||||
| Description | a ListView with style vsIcon and LargeImages Clicking on currently non selected item: * makes the clicked item selected * the previous selected item becomes non selected. However, if on OnChange event of the ListView we just access the selected property of the Item parameter, the behaviour changes. Clicking a non selected items still retained the previous selected item. | ||||
| Steps To Reproduce | Compile and run the attachment: We can see the weird behaviour if we tick the checkbox. | ||||
| Additional Information | The OnChange procedure: procedure TForm1.ListView1Change(Sender: TObject; Item: TListItem; Change: TItemChange); var s : String; begin s := Item.Caption ; if Self.CheckBox1.Checked then begin if Item.Selected then begin s := s + ' - selected'; end else begin s := s + ' - unselected'; end; end; Self.Memo1.Lines.Add( s ); Self.Memo1.SelStart:=Length( Self.Memo1.Text); Self.Memo1.SelLength:=0; end; | ||||

Problem only with WidgetSet Qt. Gtk2 runs fine. |
|
|
Added the widgetset. |
|
|
Please test and close if ok. I've also fixed Qt5 which had similar bug. Both will be merged to 1.8 fixes. |

I downloaded qwidgets.pas from 54694 but it didn't compile with lazarus v1.6.4, so I looked and applied the diff manually. The bug is fixed. |
